How do i rewire an air compressor from 110 volt to 240 volt

To rewire a Delta AP 400 Dust Collector to 220 Volts, you will need to obtain the right wiring and circuit connectors. You may need to consult an electrician or technician to complete the job safely.

if the grinder just hums then it is a 240 volt unit and will burn out on 110 volts
the garage power should be the same as the house 240 v
but if only 110 v that indicates that it is 1/3 of a 3 phase power supply
if it has just started then get a electrician in to check the reason for the power drop

The short answer is: No. The longer answer is, the motor and controls were designed to run on 220 Volts, and as such cannot simply be re-wired for 110 Volts. You basically have 3 options: 1) Have a licensed electrician wire in a 220V circuit to your shop/garage/shed for the compressor. 2) Change out the motor for one designed for 110V (finding one that will work could be difficult, and might require modification of mounts, spindles, gears etc and probably not worth the trouble...but technically possible) 3)purchase a step UP transformer which can turn 110V North American household current into 220V.

you'd have to change the voltage regulator, which is usually inside the motor - on newer motors, if they have a separate Power Supply, you can sometimes change it on a slide switch... keep in mind, that 230 is MUCH more effective for a device made for drawing a lot of power - that motor might draw 8-10 amps at 220, which will be 2x that if you go to 110... so, when all is said and done, it might work out cheaper to just spend like $200 and buy a new 110 unit that is similar... but again, depends what you want to use it for...

If you have a 110 volt appliance, all switches , wiring and components are made especially to handle that voltage. If you feed 220 to 240 volts into it, most certainly the machine will be unsafe and likely fail in a very short time. Purchase a step down transformer to reduce your supply voltage to 110. Most good electrical parts stores should be able to supply this.

If the motor is a dual voltage motor the wiring diagram is on the motor data plate. Otherwise replace the motor

You can't just run it on the 240 Volt supply. Check the motor nameplate. If it says it is rated for 110/220 or 115/230, or 120/240 Volts, then it is capable of running at 240V. This will require a wiring change, and you may need a larger size power cord.
The electrical diagram should be on the motor name plate or under the cover to the electrical terminals on the motor.

your motor overheated from too low a voltage if theres a manual reset try this,also replace the two motor start and run capacitors on the motor body

Hi there and first and foremost, just want to say Thank you for your service.

Generally for larger air compressors, the factory motor is designed to do the correct amount of work to power everything. Your wanted to step down from 240 volt motor to a 120 volt motor will probably not work. Let me explain why.

The factory 240 volt motor is going to produce more torque. It would be Tough to find a 120volt motor to match that amount of torque. The compressor or piston pump that the motor powers, requires a certain amount of torque, and speed. If you can dig in and find the compressor pump it should state right on the housing the required power to operate efficiently.

Another possible issue with going with a smaller motor is Shaft size. The 240 volt motor will tend to have a large shaft diameter then a 120.

I hope this helps, although a smaller motor would save you money on your electric bills, it just simply wont get the job done.

You can buy a transformer which allows all 110v power tools to work from a 240v supply. You will also need to change the plug on the compressor to a yellow 110v type. You can buy transformers for around £25 and around £3 for the plug
